|Mitogenomic sequence variation and organization. Sequence differences found among 17 bear mitochondrial genomes with respect to a previously published polar bear genome (GenBank accession no. NC_003428). Each vertical bar depicts a nucleotide difference from this reference sequence (shown at the bottom illustrating the organization of the genome into the different regions). The ancient Poolepynten bear sequence is highlighted in red.
